13. A pitfall in the cytodiagnosis of sputum of asthmatics
The sputum of an asthmatic often contains large, well-circumscribed clusters of benign columnar epithelial cells which can be misinterpreted as papillary fragments of an adenocarcinoma. Their presence is a manifestation of the excessive shedding of the mucosa of the lower respiratory tract accompanying an attack of bronchial asthma. These clusters are illust

14. Alveolar-cell carcinoma: a problem in sputum cytodiagnosis.
Cytology and histology are correlated in a series of 22 cases chosen to illustrate the differential diagnosis between clusters of benign bronchial or bronchiolar cells seen in sputum, and those of alveolar cell carcinoma or adenocarcinoma with alveolar spread. Alveolar-cell carcinoma is characterised by clusters of small epithelial cells in spherical or irre

15. Immunoelectron microscopy for rapid diagnosis of varicella-zoster virus in a complicated case of human T-cell lymphotropic virus type 1 infection.
Rapid techniques for the detection of herpes simplex virus (HSV) and varicella-zoster virus (VZV) are needed for optimal therapeutic management. VZV infection poses a serious threat, especially to seriously ill patients, for instance, immunocompromised patients. We report a case of human T-cell lymphotropic virus type 1-positive leukemia complicated by atypi

16. Has there been an information explosion in histopathology?
The numbers of papers published between 1966 and 1990 which could be of relevance to a histopathologist were assessed. The search for papers was conducted under 18 medical subject headings using the CD-Plus Medline computerised database for the years 1966, 1978, 1982, 1986 and 1990. Between 1966 and 1990 16 categories showed an increase in the number of inde

17. Tzanck smear in diagnosing genital herpes.
In 126 patients with anogenital lesions, in which herpes simplex virus (HSV) infection was suspected or included in the differential diagnosis, the results of cytodiagnosis of herpetic infection (Tzanck smear) were compared with virus culture. Cervical lesions were excluded from this study. HSV infection was proved by culture in 78 patients and was absent or

18. Use of antisera to epithelial membrane antigen for the cytodiagnosis of malignancy in serous effusions.
A new human antigen, designated epithelial membrane antigen (EMA), has recently been described on surface membranes of a wide variety of normal epithelium but not on connective tissue cells. The antigen is only weakly expressed on normal or reactive mesothelium. Increased expression of the antigen has been observed in most neoplasms of epithelial origin and

19. Expert system support using Bayesian belief networks in the diagnosis of fine needle aspiration biopsy specimens of the breast.
AIM--To develop an expert system model for the diagnosis of fine needle aspiration cytology (FNAC) of the breast. METHODS--Knowledge and uncertainty were represented in the form of a Bayesian belief network which permitted the combination of diagnostic evidence in a cumulative manner and provided a final probability for the possible diagnostic outcomes. The
